Steady green light shot down from the heavens and to close proximity to the ground (seen from my car -perhaps half a mile - 2 miles away?)- above trees. I was travelling east approaching The Junction shopping centre and the light came down around Phoenix Lake Area, not far from Lyons Bald Mountain. It was an emerald green colour, not too bright and very different from anything I have seen before. Acted in a controlled way, stopping before hitting the fround on the horizon. I was travelling to work so couldn't stop and look further. I turned off the raod and went away from the area it came down.
